In order to determine, in a cancer test using nematodes, whether or not the nematodes used in the cancer test are adequate, the present invention is characterized in that after a plate on which a urine from a subject and the nematode are set is placed, a cancer test apparatus performs imaging for quality assay of the nematode during the initial two minutes; an analysis apparatus determines a quality of the nematode using the imaging result; after taxis of the nematode is completed, the cancer test apparatus performs imaging for cancer test assay by the nematode; and the analysis apparatus determines the presence or absence of a cancer in the subject using the imaging result.

Cancer test system and method for assessing cancer test

Provided are a method, an apparatus, and a kit for detecting a neuroblastoma in a subject and/or for monitoring a therapeutic effect on the neuroblastoma, by measuring a urinary tumor marker(s) in a sample from the subject.

Moisture detection element, gas detection device, and breath inspection system

There is no small ion detecting apparatus that quickly and easily performs mass spectrometry under atmospheric pressure. Therefore, in order to solve the problem, an electrode arrangement and an electrode holding form for enabling water clusters in outside air to be detected with high sensitivity are provided. By using such solving means, it is possible to detect ions in a place having spatial constraints.

Breath alcohol content analyzer

The present invention provides a small-sized ion detecting device that quickly and simply performs mass analysis under atmospheric pressure. Accordingly, electrodes are arranged and held in the ion detecting device so as to be able to detect water clusters in ambient air with a high sensitivity. Thereby, ions can be detected even in a spatially-restricted place.

Ion detecting device

A method of quickly detecting a handmade explosive in a bottle with a low erroneous alarm frequency is provided. A sample gas generated from a bottle placed on a bottle placement space is sucked-in, and ions of the sample gas are generated by an ion source and subjected to mass analysis. The presence/absence of a mass spectrum derived from the handmade explosive is determined from an obtained mass spectrum, and the result thereof is displayed on a monitor, thereby quickly detecting the handmade explosive in the bottle or the handmade explosive adhering to the surface of the bottle at a low erroneous alarm frequency.

A living body inspection apparatus including an oscillation coil which passes an AC current, a detection coil which detects an AC magnetic field generated from the detection coil, an amplification circuit which amplifies a voltage generated by the magnetic field induced by the detection coil, a detecting unit for detecting the output signal of the amplification circuit, a low pass filter to which the output signal of the detecting unit is input, a unit for setting the oscillation coil and detection coil in first and second regions of the living body, a recording unit for recording the output of the low pass filter while the first region and the second region of the living body are moving and a displaying unit for displaying the data recorded in the recording unit or results of analysis of the recorded data.

Living body inspection apparatus

An ion source includes a body having a gas passage and an orifice. A capillary is inserted into the gas passage so that a tip portion of the capillary extends into the orifice. A gas supplier supplies a gas into the gas passage to form a gas flow through the gas passage along the capillary and through the orifice past a tip of the capillary so that the gas flow sprays a sample solution flowing through the capillary from the tip of the capillary. A flow controller regulates a pressure of the gas in the gas passage to adjust a characteristic value F/S to a predetermined value, where F is a flow rate of the gas flow at standard conditions (20&#xb0; C., 1 atmosphere), and S is a difference between a cross section of the orifice and a cross section of the tip portion of the capillary in the orifice.

A step () of deciding if ions of peculiar m/z are present is executed on the basis of the results obtained by the tandem mass spectrometry. An alarm is issued according to the decision result step (). Thus, fast and less-misreporting detecting can be performed.
